创建一个接口，再里面定义方法
package com.example.taidl;
interface ICalcAIDL
{
int add(int x , int y);
int min(int x , int y );
}
build一下gen目录下会生成ICalcAIDL.java文件
/*
* This file is auto-generated. DO NOT MODIFY.
* Original file: /Users/dream/Downloads/android/androidProject/TAIDL/src/com/example/taidl/ICalcAIDL.aidl
*/
package com.example.taidl;
public interface ICalcAIDL extends android.os.IInterface
{
/** Local-side IPC implementation stub class. */
public static abstract class Stub extends android.os.Binder implements com.example.taidl.ICalcAIDL
{
private static final java.lang.String DESCRIPTOR = "com.example.taidl.ICalcAIDL";
/** Construct the stub at attach it to the interface. */
public Stub()
{
this.attachInterface(this, DESCRIPTOR);
}
/**
* Cast an IBinder object into an com.example.taidl.ICalcAIDL interface,
* generating a proxy if needed.
*/
public static com.example.taidl.ICalcAIDL asInterface(android.os.IBinder obj)
{
if ((obj==null)) {
return null;
}
android.os.IInterface iin = obj.queryLocalInterface(DESCRIPTOR);
if (((iin!=null)&&(iin instanceof com.example.taidl.ICalcAIDL))) {
return ((com.example.taidl.ICalcAIDL)iin);
}
return new com.example.taidl.ICalcAIDL.Stub.Proxy(obj);
}
@Override public android.os.IBinder asBinder()
{
return this;
}
@Override public boolean onTransact(int code, android.os.Parcel data, android.os.Parcel reply, int flags) throws android.os.RemoteException
{
switch (code)
{

return true;
}

int _arg1;

int _result = this.min(_arg0, _arg1);

return true;
}
}
return super.onTransact(code, data, reply, flags);
}
private static class Proxy implements com.example.taidl.ICalcAIDL
{

Proxy(android.os.IBinder remote)
{
mRemote = remote;
}
@Override public android.os.IBinder asBinder()
{
return mRemote;
}
public java.lang.String getInterfaceDescriptor()
{
return DESCRIPTOR;
}
@Override public int add(int x, int y) throws android.os.RemoteException
{
android.os.Parcel _data = android.os.Parcel.obtain();

int _result;
try {

}
finally {

}
public int add(int x, int y) throws android.os.RemoteException;
public int min(int x, int y) throws android.os.RemoteException;
}
新建一个Service
package com.example.taidl;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;
public class CalcService extends Service{
private static final String TAG = "server";
public void onCreate()
{
Log.e(TAG, "onCreate");
}
public IBinder onBind(Intent t)
{
Log.e(TAG, "onBind");
return mBinder;
}
public void onDestroy()
{
Log.e(TAG, "onDestroy");
super.onDestroy();
}
public boolean onUnbind(Intent intent)
{
Log.e(TAG, "onUnbind");
return super.onUnbind(intent);
}
public void onRebind(Intent intent)
{
Log.e(TAG, "onRebind");
super.onRebind(intent);
}
private final ICalcAIDL.Stub mBinder = new ICalcAIDL.Stub() {
@Override
public int min(int x, int y) throws RemoteException {
return x + y;
}
@Override
public int add(int x, int y) throws RemoteException {
// TODO Auto-generated method stub
return x - y;
}
};
}
创建了一个mBinder对象，并在Service的onBind方法中返回
注册Service
<service android:name="com.example.taidl.CalcService">
<intent-filter>
<action android:name="com.example.taidl.calc" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</service>
我们一会会在别的应用程序中通过Intent来查找此Service；这个不需要Activity，所以我也就没写Activity，安装完成也看不到安装图标，悄悄在后台运行着。服务端编写完毕。下面开始编写客户端:
package com.example.tclient;
import com.example.taidl.ICalcAIDL;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;
import android.view.View;
import android.widget.Toast;
public class MainActivity extends Activity {
private ICalcAIDL mCalcAidl;
private ServiceConnection mServiceConn = new ServiceConnection()
{
@Override
public void onServiceDisconnected(ComponentName name)
{
Log.e("client", "onServiceDisconnected");
mCalcAidl = null;
}
@Override
public void onServiceConnected(ComponentName name, IBinder service)
{
Log.e("client", "onServiceConnected");
mCalcAidl = ICalcAIDL.Stub.asInterface(service);
}
};
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
/**
* 点击BindService按钮时调用
* @param view
*/
public void bindService(View view)
{
Intent intent = new Intent();
intent.setAction("com.example.taidl.calc");
bindService(intent, mServiceConn, Context.BIND_AUTO_CREATE);
}
/**
* 点击unBindService按钮时调用
* @param view
*/
public void unbindService(View view)
{
unbindService(mServiceConn);
}
/**
* 点击12+12按钮时调用
* @param view
*/
public void addInvoked(View view) throws Exception
{
if (mCalcAidl != null)
{
int addRes = mCalcAidl.add(12, 12);
Toast.makeText(this, addRes + "", Toast.LENGTH_SHORT).show();
} else
{
Toast.makeText(this, "服务器被异常杀死，请重新绑定服务端", Toast.LENGTH_SHORT)
.show();
}
}
/**
* 点击50-12按钮时调用
* @param view
*/
public void minInvoked(View view) throws Exception
{
if (mCalcAidl != null)
{
int addRes = mCalcAidl.min(50, 12);
Toast.makeText(this, addRes + "", Toast.LENGTH_SHORT).show();
} else
{
Toast.makeText(this, "服务器未绑定或被异常杀死，请重新绑定服务端", Toast.LENGTH_SHORT)
.show();
}
}
}
将服务端的aidl文件完整的复制过来，包名一定要一致。
